This guy had the idea to make a high-speed photography setup using one, instead of the more direct circuits usually involved.

The charger circuit and control algorithm was implemented using an Atmel ATMega16 microcontroller and WinAvr GNU GCC compiler. 3,4 With an 8-MHz clock rate, the algorithm's ChargerSubfunction ...

This Design Idea employs the Microchip PIC10F222 single-chip microcontroller. You program this microcontroller’s internal memory using the MCLR pin. As the title, “ Use the MCLR pin as an output with ...
